According to the latest report, Nvidia will abandon the "enthusiast key" move for enabling 3-way and 4-way SLI on GTX 1080 and GTX 1070 graphics cards as it will be unlocked but it will also only work on synthetic benchmarks and some games.
As we suspected back when Geforce GTX 1080 and Geforce GTX 1070 were launched, Nvidia has completely decided not to support anything beyond 2-way SLI on its Pascal GTX 1080 and GTX 1070 graphics cards.
While Nvidia said earlier that it will offer certain "enthusiast key" for those looking to benchmark 3-way and 4-way configurations, it appears that this won't be the case.
According to a report from PCPer.com, the enthusiast key will not longer be required and 3-way/4-way SLI will work and be supported in future graphics but such SLI will only work in certain games as well as synthetic benchmarks, meaning it will only matter to review sites, overclockers and some enthusiasts.
While we are not sure that anyone would require more than two Pascal-based GTX 1080 graphics cards, the 3-way/4-way SLI will work but only in certain applications.
Nvidia was keen to note that its High Bandwidth SLI bridge is the way to go and will focus its efforts on 2-way SLI.
